Ask the Expert: Should Diabetics Consume Artificial Sweeteners Like Aspartame?

Artificial Sweeteners


Is it advisable for a diabetic patient to consume artificial sweeteners such as aspartame, saccharin etc?


Artificial sweeteners (also known as non nutritive sweeteners; NNS) are safe to be used by the general public, people with diabetes, pregnant and lactating women as part of their strategy in managing blood sugar level or total energy intake. It is a particularly helpful choice for those who love sweetened beverages but are afraid of extra calories and carbohydrates.

Having said that, every coin has two sides. There are numerous research showing that the usage of NNS is associated with:

  • Increased risk of cancer
  • Increased hunger which eventually leads to weight gain
  • Possibility of allergic reaction such as skin irritation and swelling
  • Alteration of gut system such as bloated stomach, nausea, and vomiting
  • Mental illnesses such as depression and anxiety

However, there is still a lack of scientific evidence, especially long-term studies, to support the cons above.

So, we go back to the basics – use wisely! Try to train your taste buds for less sugar and / or less sweet and enjoy the true flavour of food.

Below are some of the commonly used NNS approved by the FDA in the United States.
